Thank you for the replies!
I did not know the 5000 BTU unit was a window unit... that would not be an option for me. Assumed that would have been a roof mounted unit... there I go assuming again!
I looked into switching the coach over to 50 AMP service already, but the cost on that is not a option... way to expensive and not practical for us as we plan on trading in our coach for a newer, slightly larger, model in about 3 years. The new coach will definitely be a 50 AMP one.
The A/C tech that replaced our A/C unit stated he could install another Coleman Mach 15 in the bedroom and run the dedicated 110v/20amp line to the side of the coach, that plugs into the pedestal by itself, for about $1200 (maybe less if he needs the money aka business is slow).
We really don't go anywhere that we cant plug in at, so not being able to run both off the generator is fine with me. I only run the generator to power the main living area A/C unit when we are traveling to our destination... that plus the driver cabin A/C keeps the coach cool enough for us during travel.
